No rest for the wicked!
Here is Blocs 3.5.5 beta build 3. This release addresses a range of issues, bumps the Menu Manager limit to 60 and adds additional fallback to protect the pre-loader from potential errors.
Anyway, you can download the latest beta version of Blocs 3.5.5 here.
Thanks for taking your own time to help test the latest version of Blocs!
